摘要
为了建立筒叶花月离体快繁技术体系,进行商业化生产。本研究以筒叶花月叶片为外植体材料,对其进行诱导、分化、增殖、生根培养。结果表明,采用叶片平放方式,培养基为MS+KT1mg/L+6-BA1.2mg/L+NAA1.5mg/L的浓度配比,适合筒叶花月叶片愈伤组织的诱导;采用培养基为MS+KT1mg/L+6-BA0.6mg/L+NAA0.5mg/L的浓度配比,适合筒叶花月不定芽的分化培养;培养基为MS+6-BA1mg/L+NAA0.05mg/L的配比,适合筒叶花月不定芽的增殖。培养基为MS+KT1mg/L+6-BA0.6mg/L+NAA1mg/L的配比,适合筒叶花月不定根的诱导培养。
In order to establish a rapid propagation system for Crassula obliqua Gollum in vitro and on the purpose of commercial production. In this study, the leaves of Crassula obliqua Gollum were selected as explant material to induce, proliferate, differentiate and culture rooting in vitro. The results showed that: A highly efficient regeneration system of Crassula obliqua Gollum was initially established. The optimal hormone combinations for adventitia ous bud initiation were MS medium with KT 1 mg/L, 6-BA 1.2 mg/L and NAA 0.5 mg/L, and the leaf position was horizontal onto the medium. The hormone combinations of MS medium with KT 1 mg/L, 6-BA 1.2 mg/L and NAA 2 mg/L was beneficial for callus differentiation, and the leaf position was vertical onto the medium, respectively. MS mediu with KT 0 mg/L, 6-BA 1 mg/L and NAA 0.05 mg/L was used as adventitious bud increment medium. MS mediu with KT 1 mg/L, 6-BA 0.6 mg/L and NAA 1 mg/L can be used as rooting medium.
